Accusations aside, does anyone have a relatively simply program to
do ray-tracing on PC.  It might require math coprocessor or massive amout of
EMS or XMS memory or RAM drive, and it might take 2 weeks to do the job,
but just so I can see what myself what's in there.  (please, no books, unless
it's got a ray-trace program in it).

Thanks in advance.
